After watching the scene with the director, Joon-won knew he made a mistake. It was not an intentional mistake but a mistake caused because he was a bit too good and in a hurry. His lines came off a bit quicker than he expected them to and even though he had to do the heavy lifting in the scene he should also play second fiddle to Mi Ji as she was the Heroine of the movie. His expression was a bit too good and so compared to him Mi Ji's expressions and acting seemed to dim a little.
The director turned towards him as they finished watching the scene and said, "It looks like you figured out the problem. If it's a bit tough for you to reel it in we can split the scene and covers it up in post-production. What do you say?"
"I am very sorry for the trouble, but it should be alright. I'll fix it up with time."
"Alright then, everyone, get ready. Let's finish it off this time and go out for lunch." the director clapped as he looked around the set.
